Model RXEF250

Description PolySwitch™ RXE Series TE PolySwitch ™ RXE stands for low holding current series (as low as 50mA) and high rated voltage (up to 72V) devices. Commonly used for printers, satellite video receivers, industrial controls, transformers, computer motherboards, modems, USB hubs, ports and peripherals, gaming consoles, mobile phones, fax machines, analog and digital line card applications. The rated current is 50mA to 15A, and the rated voltage ranges from 6V (for computer and electronic applications) to 99V. The fast acting low impedance complies with RoHs, halogen-free, printed circuit board wire end (resettable fuse), and printed circuit board wire end resettable fuse with radial leads has the following characteristics: all pass through UL, CSA, and TUV Certification can protect electrical and electronic circuits from damage caused by excessive current. It can quickly switch from a low resistance state to a very high resistance state through electrical overload or short circuit. After correcting the fault state and turning off the power, it can quickly and automatically reset and return to the low resistance state. Features: It can perform thousands of automatic self resets. Maintenance free small models, no need for fuse holders. Main applications: security system power supply and transformer power switch devices, automotive and medical equipment instruments and control computers and peripheral devices, audio, video, and telecommunications
